Story Highlights

The Boston Red Sox and Boston Bruins postponed their scheduled Friday games because of the continuing manhunt in the Boston Marathon bombing case.

The Red Sox said on Twitter that their decision to postpone the game against the Kansas City Royals was made to "support efforts of law enforcement officers." They did not announce a makeup date.

The Bruins-Pittsburgh Penguins game at TD Garden will be played at a 12:30 p.m. matinee on Saturday, if conditions allow. The Bruins will say by 8:30 a.m. Saturday if the game is on. The Penguins, who were scheduled to play the Buffalo Sabres Saturday, will play that game Tuesday instead.

Many colleges in the region also postponed athletic events. Harvard, for instance, postponed all athletic events until further notice, even road games, except for teams that were already on site at road games, such as the men's lacrosse team that plays at Princeton Friday.

Boston College said on its athletics web site that Friday's women's tennis match against North Carolina was canceled. The school also canceled Saturday's spring football game and all related events as well as all home athletic events scheduled for Saturday.

"Our first priority is ensuring the safety of our student-athletes, coaches and spectators," athletics director Brad Bates said in a statement. "Our local law enforcement community has done a phenomenal job this past week, and we do not want our events to serve as a distraction.

"Furthermore, now is a time for reflection to honor those who have been tragically killed and injured this past week and to allow our community to heal. The entire Boston College family stands with those who have been affected by this week's events. Together we will persevere and emerge stronger and more unified than ever."
